Wood Newspaper I 23 Claims,

This invention relates to improvements in rotary stuffing machines, thatis, a machine wherein one section of a newspaper or the like is insertedinto another section and the two sections then inserted into a thirdsection and so on, according to the number of units or sections whichmay complete the entire issue of the newspaper;

The modern trend, particularly in Sunday newspapers, calls for a numberof difierent sections, the main or primary news section'and othersections, some printed in black, others in color, including rotogravuresections, book sections and other special sections.

The practice generally followed is to print the various sections aheadof the date of issue which they bear, and in fact many of these sectionsare printed a. week or more in advance, some of them during thepreceding week and the latest current news or main section on Saturdaynight or early Sunday morning.

To assemble all of these difierent sections intov one is quite anarduous and time-consuming task.

At the present time the usual practice is to stuff or insert one sectioninto the other and so on by hand or manually.

In some of the larger newspaper oflices machines are employed which dothis work of stufling or inserting the sections into each otherautomatically. In general, however, this is not satisfactory and is avery slow operation due in part to the large'number of reciprocatingparts and complicated mechanism required.

The object and purpose of the present invention is to so construct arotary stufiing machine,

such sections and after all sections have been inserted then to aclosing device and then conveyed away from the machine.

It is quite important that the lower section being removed from thehopper or unit containing, such sections be removed therefrom in or by arotary movement, that is peeled there-- from, particularly in view ofthe fact that the papers, due in some instances to the printing of theproducts on rotogravure presses will not permit of a sliding movement.of one section section, so that subsequent sections may be insertedtherein.

A further object'is to provide a cam shaped guide or closing device forclosing the section after the assembly has been completed, that is,after all sections have been properly inserted in the preceding sectionor sections.

Fig. 15 is a section through the, closing device on line l5l5 of Fig. 2;and Y Fig. 16 is a section through the closing device on line Ill-46 ofFig. 2.

The current news sections are stacked in the hopper l and the sectionsto be inserted therein stacked in the hoppers 2 and 3. Vacuum or suctioncylinders 4 and 5 are provided, the suction being through the openings 6and 1 leading into the openings 8 and 9 respectively which are connectedto a suction apparatus. The bottom section IU of the stack of sectionsis rolled off of the sections above it by means of vacuum cylinder 4.This section it will be readily seen is rolled off the bottom of thepile without any sliding motion between the sections. The vacuumcylinders 4 and rotate in an opposite direction to the periphery of themain cylinder l I and at the same surface speed. Belts l2 and I3 supportthe stack of sections while the vacuum cylinder 4 carries the lowersection and delivers it to the conveyor l4 and the vacuum cylinder 5arrives in position to remove the next lower section from the stack.

The belts l2 and I3 also run in a direction opposite to that of theperiphery of the cylinder II and at an equal speed. There is thereforeno relative movement between these belts l2 and I3 and the stack ofpaper sections.

The belts l2 and I3 are driven by pulleys l5 and I6, which pulleys arein turn driven by the vacuum cylinders through gears l1 and I8. Thevacuum cylinders are driven through fixed integral gear rings l9 and 20.

These belts l2 and I3 it will be seen, pass beneath and support oppositesides of the lower section in the hopper and thereby support the stackduring the intervals of time between vacuum cylinder operation, that is,between the time when one section has' been removed by cylinder 4 andthe cylinder 5 reaches its operative position beneath the stack forremoving the then lowermost section.

The cylinder H rotating with the shaft 2| and the lower section 10 ofthe stack having been rotatively removed from the bottom of the stack isheld fast on the vacuum cylinder 4 until said cylinder 4 reaches aposition at the bottom of the cylinder in a position corresponding tothat 00- cupied by vacuum cylinder 5, as shown in Fig. 3, whereupon thevacuum holding the section In to the vacuum cylinder 4 is released andthe section II) deposited on the conveyor l4. This conveyor isconstantly running in a direction in line with the axis of the cylinderl I.

The section 10 is then carried by theconveyor l4 in a fiat conditionbeneath a vacuum or suction wheel 22, which vacuum wheel by suctionlifts or opens up the section H! at the corner 23 opposite the fold onthe leading edge of the section, the section l0 constantly movingforward or along with the conveyor. This section with its corner 23lifted then encounters a plow shaped former or guide 24 by which thesection I0 is further opened and is carried in this opened conditionbeneath the next unit H which feeds the first section to be inserted tothe conveyor in a manner similar to that previously described as to theremoval of the sections from hopper l. Instead, however, of the bottomsection of the sections contained in-hopper 2 being fed to the conveyorsaid section is dropped between the opened portion of section 10 and theremainder of said section. Section ID at this time has reached aposition below the cylinder removing sections from hopper 2.

If further sections from other units are to be inserted the section IDwith the section from hopper 2 inserted therein is carried forward bythe conveyor beneath another vacuum or suction wheel 22, which, aspreviously, lifts a portion of the outer section NJ and the section'with the insert is carried to another opener or guide 24 and held inopen position until a section from the next unit is in a similar mannerdelivered between the open portions of the section.

When there are no further sections to' be inserted the section I0 withits insert or inserts is then carried forward by the conveyor to aclosing former or guide 25 through means of which the lifted portion ofsection I0 is closed or folded down upon the inserted sections.

A vacuum or suction wheel 22 of a similar construction is utilized inconnection with each unit as in the first unit and a similar guide oropener is used following each unit. But one closing former or guide isused after the last unit.

The mechanism shown in section in Fig. 3 for rotatively removing thelower section from the stack of sections in its respective hopper isidentical in each of the several units and operates in the same manner.v

The closing former or guide 25 is so shaped that the lifted portion ofsection l0 contacts with the side of the closing form-er 25, in the opencondition of the section, as shown for example, in Figs. 14, 15 and 16.The continued movement of the section ID with its inserted section Illaalong the closing former 25 gradually causes the lifted portion ofsection It] to be folded down upon the inserted section 10a. Thecompleted assembly of the several sections is then conveyed away fromthe machine for delivery.

As stated above, the several vacuum or suction cylinders 22 aresubstantially identical in structure and operation,,and as many as needbemay be provided.

After the various sections, or as many as are desired to be inserted inthe outside section have been acted upon, the outer section or openportion of the first section is closed by a former 25, which is locatedin a substantially reverse position to that in which the opening former24 is located.

The inserted sections, of course, are not opened or acted upon by theformers but only the main or current news section which is taken fromthe hopper I.

After all of the sections have been inserted and the open portion ofsection In closed, the assembly of the various sections is delivered ontoabelt or conveyor 26 for delivery to any de sired station.

The belts l2 and I3 are endless belts which travel over a series ofrollers 21 and 28, the rollers being joumaled in a series of openings 29and 30 of the housing or casing shown in Fig. 9.
